4 days of factor 3 forecast by MetO starting tomorrow. Late for a rash of 3s. Top up on VitD before the big dark.

Reading just nipped 1.5 yesterday. Today there is thin cloud across the sun but the cloudbank ends just a few miles east. Might walk there.
Here, sun's angle now just short of 20 degrees.

 Wonder if we can do better than last year in the UV stakes. Reading's readings:

 a poor year really with even the August heatwave hitting just 5s and about 6.

 First 2 last year: 17/2
First 3 17/3
First 4  26/3
First 5  10/4 (not bad to this point)
First 6 5/5
First 7 17/5 
Then poor. No pre-solstice 8. 
8 recorded only on 7/7 in July.

Fun prediction game? 5 day windows allowed to allow for weather. 
First 5, 6 and 7: 5- 3-7 April
                         6: 27 Apr- 1 May
                         7:  12-16 May.

We'll see!
🙂

Seeing you said poor in the summer months it was true as it was very poor summer here due to HP bringing too much clouds with it so only clear skies early and late which no use for recording sun index which need midday peak sunlight.  I hoping this year summer to be much better than last year to see more sun between 9am to 3pm.

Here is the sunshine anomaly map for last summer.

Yes, apologies, I was unclear; I meant poor in terms of high UV values, rather than hours of sunshine, which is of course far more relevant to most of us!

Allthat said, I feel sure I can remember even Aberdeen being forecast 6s at some point last summer.

 A 1.8 then 1.7 in Reading, and a 1.9 in Camborne.
Won't say I can feel it yet, but the light is changing, slowly, and the sunat 21.5° altitude is just clipping the tops of the school trees.

Pretty much 5:30 now down here for dusk, a few more weeks to go before spring, from a daylight perspective at least, rears its head.

1.8 in Reading today. The 2 is edging closer although bizarrely, the Beeb is forecasting Medium UV for next week in Winchester.

Can't paste and of course the link changes regularly, but isn't M a 3 at least? I'd get a sunny 2 from here on in (although my mean earliest 2 seems to be about the 17th) but a 3? Now? Not possible surely unless a significant O3 dissipation is imminent.

Reading looks like a 1.9 today although the graph alignment might be out with a peak at 1130-1145 then a steady drift cown (not the sudden reduction you'd get when it clouds over).

When the sun reaches 25 degrees above horizon there's a marked step change in solar reaching the surface, as the atmosphere reflects or refracts more energy downwards rather than back into space from above that angle.
Here that happens about 22nd Feb this year but further south will have been there at least two weeks already.

It's also coincidentally the time there's a marked change in the quality of light. From my POV, spring arrives in mid-February!

Surprised Reading looks to have easily achieved a 2 today, it was pretty cloudy, very few glimpses of the sun. Next up is the 3.
